php获取访问者IP地址汇总

   php获取访问者IP地址汇总

        在很我的时候我们需要得到用户的真实IP地址,例如,日志记录,地理定位,将用户信息,网站数据分析等,其实获取IP地址很简单$_SERVER[\'REMOTE_ADDR\']就可以了。下面我们就来给大家汇总一下常用的几种获取IP地址的方法。

  //方法1:

$ip = $_SERVER["REMOTE_ADDR"];

echo $ip;

  //方法2:

  代码如下:

  $user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];

  $user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];

  echo $user_IP;

function getRealIp()

{

$ip=false;

if(!empty($_SERVER["HTTP_CLIENT_IP"])){

$ip = $_SERVER["HTTP_CLIENT_IP"];

}

if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {

$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);

if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }

for ($i = 0; $i

if (!eregi ("^(10│172.16│192.168).", $ips[$i])) {

$ip = $ips[$i];

break;

}

}

}

return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);

}

echo getRealIp();
